Sources of CICS data

CMP, BMC AMI Ops Monitor for CICS, or TMON for CICS gather data that reflect the use of system resources during user-specified operating intervals and write the information to an output data set.

From CMP, BMC AMI Ops Monitor for CICS, or TMON for CICS data, UIE derives the following information:

• Transaction count
• Application CPU usage per transaction
• Average response time
• Total I/O count per transaction

By default, UIE processes the IBM 110 data for each CICS region for which 110 data is found. However, before processing any CICS data, UIE checks for the presence of BMC AMI Ops Monitor for CICS and TMON for CICS data sets. If either BMC AMI Ops Monitor for CICS or TMON for CICS data is found, the following actions occur:

• If only BMC AMI Ops Monitor for CICS data is found, processing of 110 data is turned off for all systems and the BMC AMI Ops Monitor for CICS data is considered the only CICS data source.
• If only TMON for CICS data is found, processing of 110 data is turned off for all systems and the TMON for CICS data is considered the only CICS data source.
• If both BMC AMI Ops Monitor for CICS and TMON for CICS data are found, processing of 110 data and TMON for CICS data are turned off for all systems and BMC AMI Ops Monitor for CICS is considered the only CICS data source.

If you want to process a mixture of CICS data sources, you can use the APPLControl command to indicate which data source should be processed for a specific system or CICS region. For more information about the APPLControl command, see APPLCONTROL.
